17
      by the loop-header phi (as opposed to the other uses of k that are
18
      defined in the loop), in which case we exercise the fact that we
19
      reuse the same vector def-use-cycle for both uses.
20
      Peeling to align the store is also applied. This peeling also aligns
21
      the load (as they have the same misalignment).  */
